It has since become the prototype and eponym for a class of variable stars called W Ursae Majoris variables. [10] This system consists of a pair of stars in a tight, circular orbit with a period of 0.3336 days, or eight hours and 26 seconds. [5] During every orbital cycle, each star eclipses the other, resulting in a decrease in magnitude. The ...
Seen from a superior planet, an inferior planet on the opposite side of the Sun is in superior conjunction with the Sun. An inferior conjunction occurs when the two planets align on the same side of the Sun. At inferior conjunction, the superior planet is "in opposition" to the Sun as seen from the inferior planet (see the diagram).

These stars are estimated, via Kepler's third law, to have periods ranging from a few years to thousands of years. A visual binary consists of two stars, usually of a different brightness. Because of this, the brighter star is called the primary and the fainter one is called the companion.
A mysterious object unlike anything ever seen before has been spotted by astronomers. Observations of the “spooky” item showed it releasing a giant burst of energy three times an hour.
Analysis of a color-age star formation angle sequence of the Fourier components establishes that the strong outer pair is the leading pair A Fourier component image of the arm pairs is shown with one of the pair of arms marked for the newly discovered inner CCW pair (black dots) as well as one of the already known (CW) outer pair (white dots).
The most common kinds of binary system are binary stars and binary asteroids, but brown dwarfs, planets, neutron stars, black holes and galaxies can also form binaries. A multiple system is similar but consists of three or more objects, for example triple stars and triple asteroids (a more common term than 'trinary').
